Lots of advice there guys thanks! Sounds like I should be okay for a while with the mani, I can see how an aftermarket one may give a few more horses but they are quite pricey. I don't wanna buy a CT9 manifold because it would be useless when I go TD04. Here's some pics of the porting: I think the boost is a bit unstable because of the gutted cat so I'll look for a proper decat Yep I have a boost gauge, didn't have the T-Piece to plumb it in but I have one know, will be fitted when I'm next home I reckon 2.5 inch is perfect, most aftermarket ones are 2.5"+ and it'll be sufficient for TD04 too Cool I'll keep an eye out for a catch tank, should they have a bleed screw on the bottom or a removeable top? And a breather on top rather than being airtight? In terms of a boost controller, they seem to be quite expensive I've done a bit of reading on here and it seems a Dawes device/Turbosmart boost controller offers a lot of the advantages of an EBC at a fraction of the price? MBC thread 1 MBC thread 2 Okay by the sounds of it I probably won't need a fuel pump until I go TD04? I'll be on the lookout for a braided oil feed. Are used ones okay? Trying to keep the costs down lol ;)
